owl carousel creates components 3 times

[brot1234]

Hi,
I have this little project here

My template

<owl-carousel-o [options]="carouselOptions">
  <inf-new-arrivals *carouselSlide></inf-new-arrivals>
  <inf-team-charta *carouselSlide></inf-team-charta>
</owl-carousel-o>

The corresponding .ts

export class AppComponent {
  carouselOptions: OwlOptions = {
    loop: true,
    autoplay: true,
    autoplaySpeed: 2000,
    autoplayTimeout: 2500,
    dots: true,
    responsive: {
      0: {
        items: 1
      }
    },
  }
}

And one component

export class TeamChartComponent {
  employees$: Observable<string[]>;

  constructor(private calendar: CalendarService) {
    console.log("WOW")
    this.employees$ = this.calendar.getEmployeeReservations('ID',NUMBER);
  }
}

Now what happens here is that the constructor is called 3 times, so I see 3 "WOW"s in my console.
I believe this isn't supposed to be like that.
